Like you, I went from a Ford F-150 to Silverado. I had a nicely loaded 2016 Ford F-150 XLT Supercrew 4×4, the best one WITHOUT leather. I traded it in 2019 for a Silverado RST 4×4, the best one WITHOUT leather.
The bed in the 5.7-ft bed Silverado is a LOT bigger than the bed in the 5.5-ft bed F-150. I could sleep diagonally and have a foot above my head to spare while both my head and feet were touching the corners, forcing me to opt for the 6.5-ft F-150 XLT, but not with the Silverado. That's becuase the insides are more efficient and wider.
The RST is definitely more exciting to drive but the others here and I have had issues with the twin-tube shocks, and I would not recommend the RST if it is four-wheeling performance you seek. The F-150 handled rocks and dirt roads very well, I used it every day on the ranch. Highway cruising, the F-150 wins. Four wheeling, the F-150 wins. It really is versatile. Seats, I'd say the Silverado wins.
One thing the F-150 has is the keypad outside the door. I can leave my keys inside and lock it in without having to worry about it. I do that many times if I leave it parked at the airport and go somewhere. I can't do that with the Silverado.
The 5.8 V8 in the Silverado may have a little less power, but gets much better gas mileage than the 5.0 V8 in the F-150. And that's based on the computer.. F-150's MPG calculations are a lot more optimistic than the Silverado's so I know I am even getting better gas mileage in the Silverado. After 400 miles, my Silverado shows 22.1 mpg, not bad for a V8 with 4×4. My F-150's best was 16.8 mpg (probably 15 mpg if I measured it by hand instead of using the computer).
Due to issues I've had with handling, I may go back to the F-150. I am hoping the new 2020 models and after that are better than the 2016 I owned.
